At this point, and given a very successful track-record with smaller pieces, I will focus on making larger resin-castings rather than a 3D printer with perhaps-marginal resolution. The nice thing about silicon molds is that they may be used over and over after a little bit of care in the making. I will let 3D printer technology evolve for a bit before investing at what I see is the level necessary to be useful for my intentions.

Thank you for all your input.
